Conference PaperPhase-Matching Schemes for Back-Conversion Suppression in Nonlinear Wave Mixing: Towards Ultra-High Efficiency and Ultra-Broad BandwidthMoses, JeffreynullBy suppressing the conversion-back-conversion cycles typical of optical parametric processes through novel phase-matching schemes, octave-spanning frequency conversion and highly efficient parametric amplification can be achieved. Several recent developments will be reviewed.2020-05-01102111692020 Photonics North (PN)1 to 1https://doi.org/10.1109/PN50013.2020.91669461944653National Science Foundation
